These types of lasers are integrated into end customer systems by techs at a factory. They are very simple to setup from the black box level of understanding. All you do is plug in water (blue hose in and red hose for out) since the electrical system is typical a box that simply plugs into the laser head and the wall outlet. The only factor that could affect the output power that's not on the controls would be the water temperature.
